After waiting about an hour, it started up but stopped and will not start at all now. Battery is new.

Hi,

What you described sounds like it could be related to a faulty crankshaft position sensor. When they begin failing, heat adversely will affect them.

Do me a favor. Take a look through this link and let me know if it mirrors what you experience.

Since the vehicle won't start, we need to check for both spark to the plugs and fuel. If the crankshaft sensor is bad, there will likely be no spark.

Here is a link that explains how to test for ignition spark.

Also, see if it will start for a couple of seconds and then stall using starting fluid. If it does, then we know it is a fuel-related issue.

Try this and let me know what you find. Also, hang in there. We get it running again.

Take care,

Joe
